One way that also works is putting it this way in the first line of the your target:

your-target: $(eval SHELL:=/bin/bash)
    @echo "here shell is $$0"

You need to install ssh2 lib

sudo apt-get install libssh2-php && sudo /etc/init.d/apache2 restart

that should be enough to get you on the road

unfortunately, with "mvim -v", ALT plus arrow windows still does not work. I have not found any way to enable it :-(

data.rename(columns={'gdp':'log(gdp)'}, inplace=True)

The rename show that it accepts a dict as a param for columns so you just pass a dict with a single entry.

Pure Bash, use parameter substitution:

BundleConfig is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)

To add this file, first you need to add the Microsoft.AspNet.Web.Optimization nuget package to your web project:

Install-Package Microsoft.AspNet.Web.Optimization

Then under the App_Start folder create a new cs file called BundleConfig.cs. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):

using System.Web;
using System.Web.Optimization;

namespace CodeRepository.Web
{
    public class BundleConfig
    {
        // For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.validate*"));

            // Use the development version of Modernizr to develop with and learn from. Then, when you're
            // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js",
                      "~/Scripts/respond.js"));

            bundles.Add(new StyleBundle("~/Content/css").Include(
                      "~/Content/bootstrap.css",
                      "~/Content/site.css"));
        }
    }
}

Then modify your Global.asax and add a call to RegisterBundles() in Application_Start():

using System.Web.Optimization;

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

Write-Back is a more complex one and requires a complicated Cache Coherence Protocol(MOESI) but it is worth it as it makes the system fast and efficient.

The only benefit of Write-Through is that it makes the implementation extremely simple and no complicated cache coherency protocol is required.

You seem to have misunderstood how character classes definition works in regex.

To match any of the strings 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, or 12, something like this works:

0[1-9]|1[0-2]

References

• regular-expressions.info/Character Classes
  • Numeric Ranges (have many examples on matching strings interpreted as numeric ranges)

Explanation

A character class, by itself, attempts to match one and exactly one character from the input string. [01-12] actually defines [012], a character class that matches one character from the input against any of the 3 characters 0, 1, or 2.

The - range definition goes from 1 to 1, which includes just 1. On the other hand, something like [1-9] includes 1, 2, 3, 4, 5, 6, 7, 8, 9.

Beginners often make the mistakes of defining things like [this|that]. This doesn't "work". This character definition defines [this|a], i.e. it matches one character from the input against any of 6 characters in t, h, i, s, | or a. More than likely (this|that) is what is intended.

References

• regular-expressions.info/Brackets for Grouping and Alternation with the vertical bar

How ranges are defined

So it's obvious now that a pattern like between [24-48] hours doesn't "work". The character class in this case is equivalent to [248].

That is, - in a character class definition doesn't define numeric range in the pattern. Regex engines doesn't really "understand" numbers in the pattern, with the exception of finite repetition syntax (e.g. a{3,5} matches between 3 and 5 a).

Range definition instead uses ASCII/Unicode encoding of the characters to define ranges. The character 0 is encoded in ASCII as decimal 48; 9 is 57. Thus, the character definition [0-9] includes all character whose values are between decimal 48 and 57 in the encoding. Rather sensibly, by design these are the characters 0, 1, ..., 9.

• Wikipedia/ASCII

Another example: A to Z

Let's take a look at another common character class definition [a-zA-Z]

In ASCII:

• A = 65, Z = 90
• a = 97, z = 122

This means that:

• [a-zA-Z] and [A-Za-z] are equivalent
• In most flavors, [a-Z] is likely to be an illegal character range
  • because a (97) is "greater than" than Z (90)
• [A-z] is legal, but also includes these six characters:
  • [ (91), \ (92), ] (93), ^ (94), _ (95), ` (96)

Related questions

• is the regex [a-Z] valid and if yes then is it the same as [a-zA-Z]

It is defined as:

typedef unsigned long       DWORD;

However, according to the MSDN:

On 32-bit platforms, long is synonymous with int.

Therefore, DWORD is 32bit on a 32bit operating system. There is a separate define for a 64bit DWORD:

typdef unsigned _int64 DWORD64;

Hope that helps.

gnu/stubs-32.h is not directed included in programms. It's a back-end type header file of gnu/stubs.h, just like gnu/stubs-64.h. You can install the multilib package to add both.

The answer probably depends on what format your date is in, but here is an example using the Date class:

dt <- as.Date("2010/02/10")
new.dt <- dt - as.difftime(2, unit="days")

You can even play with different units like weeks.

I had this problem. Reinstalling the latest version of Adobe Reader did nothing. Adobe Reader worked in Chrome but not in IE. This worked for me ...

1) Go to IE's Tools-->Compatibility View menu.
2) Enter a website that has the PDF you wish to see. Click OK.
3) Restart IE 4) Go to the website you entered and select the PDF. It should come up.
5) Go back to Compatibility View and delete the entry you made.
6) Adobe Reader works OK now in IE on all websites.

It's a strange fix, but it worked for me. I needed to go through an Adobe acceptance screen after reinstall that only appeared after I did the Compatibility View trick. Once accepted, it seemed to work everywhere. Pretty flaky stuff. Hope this helps someone.

The problem is that omega in your case is matrix of dimensions 1 * 1. You should convert it to a vector if you wish to multiply t(X) %*% X by a scalar (that is omega)

In particular, you'll have to replace this line:

omega   = rgamma(1,a0,1) / L0

with:

omega   = as.vector(rgamma(1,a0,1) / L0)

everywhere in your code. It happens in two places (once inside the loop and once outside). You can substitute as.vector(.) or c(t(.)). Both are equivalent.

Here's the modified code that should work:

gibbs = function(data, m01 = 0, m02 = 0, k01 = 0.1, k02 = 0.1, 
                     a0 = 0.1, L0 = 0.1, nburn = 0, ndraw = 5000) {
    m0      = c(m01, m02) 
    C0      = matrix(nrow = 2, ncol = 2) 
    C0[1,1] = 1 / k01 
    C0[1,2] = 0 
    C0[2,1] = 0 
    C0[2,2] = 1 / k02 
    beta    = mvrnorm(1,m0,C0) 
    omega   = as.vector(rgamma(1,a0,1) / L0)
    draws   = matrix(ncol = 3,nrow = ndraw) 
    it      = -nburn 

    while (it < ndraw) {
        it    = it + 1 
        C1    = solve(solve(C0) + omega * t(X) %*% X) 
        m1    = C1 %*% (solve(C0) %*% m0 + omega * t(X) %*% y)
        beta  = mvrnorm(1, m1, C1) 
        a1    = a0 + n / 2 
        L1    = L0 + t(y - X %*% beta) %*% (y - X %*% beta) / 2 
        omega = as.vector(rgamma(1, a1, 1) / L1)
        if (it > 0) { 
            draws[it,1] = beta[1]
            draws[it,2] = beta[2]
            draws[it,3] = omega
        }
    }
    return(draws)
}

After many attempts, I found the junction approach more convenient. This is very similar on how this problem is solved in linux.

Basically it consists of having a link between c:\tools\java\default and the actual version of java you want to use as default in your system.

How to set it:

1. Download junction and make sure to put it in your PATH environment variable
2. Set your environment this way: - PATH pointing to ONLY to this jre c:\tools\java\default\bin - JAVA_HOME pointing to `c:\tools\java\default
3. Store all your jre-s in one folder like (if you do that in your Program FIles folder you may encounter some
   • C:\tools\Java\JRE_1.6
   • C:\tools\Java\JRE_1.7
   • C:\tools\Java\JRE_1.8
4. Open a command prompt and cd to C:\tools\Java\
5. Execute junction default JRE_1.6

This will create a junction (which is more or less like a symbolic link in linux) between C:\tools\java\default and C:\tools\java\JRE_1.6

In this way you will always have your default java in c:\tools\java\default.

If you then need to change your default java to the 1.8 version you just need to execute

junction -d default
junction default JRE_1.8 

Then you can have batch files to do that without command prompt like set_jdk8.bat set_jdk7.bat

As suggested from @????????????

EDIT: From windows vista, you can use mklink /J default JRE_1.8

This is impossible because generics in Java are only considered at compile time. Thus, the Java generics are just some kind of pre-processor. However you can get the actual class of the members of the list.

You are right. The code you've provided only checks if there is a network connection. The best way to check if there is an active Internet connection is to try and connect to a known server via http.

public static boolean hasActiveInternetConnection(Context context) {
    if (isNetworkAvailable(context)) {
        try {
            HttpURLConnection urlc = (HttpURLConnection) (new URL("http://www.google.com").openConnection());
            urlc.setRequestProperty("User-Agent", "Test");
            urlc.setRequestProperty("Connection", "close");
            urlc.setConnectTimeout(1500); 
            urlc.connect();
            return (urlc.getResponseCode() == 200);
        } catch (IOException e) {
            Log.e(LOG_TAG, "Error checking internet connection", e);
        }
    } else {
        Log.d(LOG_TAG, "No network available!");
    }
    return false;
}

Of course you can substitute the http://www.google.com URL for any other server you want to connect to, or a server you know has a good uptime.

As Tony Cho also pointed out in this comment below, make sure you don't run this code on the main thread, otherwise you'll get a NetworkOnMainThread exception (in Android 3.0 or later). Use an AsyncTask or Runnable instead.

If you want to use google.com you should look at Jeshurun's modification. In his answer he modified my code and made it a bit more efficient. If you connect to

HttpURLConnection urlc = (HttpURLConnection) 
            (new URL("http://clients3.google.com/generate_204")
            .openConnection());

and then check the responsecode for 204

return (urlc.getResponseCode() == 204 && urlc.getContentLength() == 0);

then you don't have to fetch the entire google home page first.

list($width, $height) = getimagesize($filename)

I was able to select (check) a radio input button by using this Javascript code in Firefox 72, within a Web Extension option page to LOAD the value:

var reloadItem = browser.storage.sync.get('reload_mode');
reloadItem.then((response) => {
    if (response["reload_mode"] == "Periodic") {
        document.querySelector('input[name=reload_mode][value="Periodic"]').click();
    } else if (response["reload_mode"] == "Page Bottom") {
        document.querySelector('input[name=reload_mode][value="Page Bottom"]').click();
    } else {
        document.querySelector('input[name=reload_mode][value="Both"]').click();
    }
});

Where the associated code to SAVE the value was:

reload_mode: document.querySelector('input[name=reload_mode]:checked').value

Given HTML like the following:

    <input type="radio" id="periodic" name="reload_mode" value="Periodic">
    <label for="periodic">Periodic</label><br>
    <input type="radio" id="bottom" name="reload_mode" value="Page Bottom">
    <label for="bottom">Page Bottom</label><br>
    <input type="radio" id="both" name="reload_mode" value="Both">
    <label for="both">Both</label></br></br>

SetX is the command that you'll need in most of the cases.Though its possible to use REG or REGEDIT

Using registry editing commands you can avoid some of the restrictions of the SetX command - different data types, variables containing = in their name and so on.

@echo off

:: requires admin elevated permissions
::setting system variable
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v MyVar /D MyVal
::expandable variable
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /T REG_EXPAND_SZ /v MyVar /D MyVal


:: does not require admin permissions
::setting user variable
REG ADD "HKEY_CURRENT_USER\Environment" /v =C: /D "C:\\test"

REG is the pure registry client but its possible also to import the data with REGEDIT though it allows using only hard coded values (or generation of a temp files). The example here is a hybrid file that contains both batch code and registry data (should be saved as .bat - mind that in batch ; are ignored as delimiters while they are used as comments in .reg files):

REGEDIT4

; @ECHO OFF
; CLS
; REGEDIT.EXE /S "%~f0"
; EXIT

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]
"SystemVariable"="GlobalValue"

[HKEY_CURRENT_USER\Environment]
"UserVariable"="SomeValue"

If you use jQuery UI's datepicker and moment.js on the same project, you should piggyback off of moment.js's locale data:

// Finnish. you need to include separate locale file for each locale: https://github.com/moment/moment/tree/develop/locale
moment.locale('fi'); 

// fetch locale data internal structure, so we can shove it inside jQuery UI
var momentLocaleData = moment.localeData(); 

$.datepicker.regional['user'] = {
    monthNames: momentLocaleData._months,
    monthNamesShort: momentLocaleData._monthsShort,
    dayNames: momentLocaleData._weekdays,
    dayNamesShort: momentLocaleData._weekdaysMin,
    dayNamesMin: momentLocaleData._weekdaysMin,
    firstDay: momentLocaleData._week.dow,
    dateFormat: 'yy-mm-dd' // "2016-11-22". date formatting tokens are not easily interchangeable between momentjs and jQuery UI (https://github.com/moment/moment/issues/890)
};

$.datepicker.setDefaults($.datepicker.regional['user']);

You can use the following function to enqueue script or style from plugin.

function my_enqueued_assets() {
    wp_enqueue_script('my-js-file', plugin_dir_url(__FILE__) . '/js/script.js', '', time());
    wp_enqueue_style('my-css-file', plugin_dir_url(__FILE__) . '/css/style.css', '', time());
}
add_action('wp_enqueue_scripts', 'my_enqueued_assets');

Try the code below. It will work if you enter multiple lines in a single column.

create table  products (prod_id number , prod_desc varchar2(50));

insert into products values(1,'test first

test second

test third');

select replace(replace(prod_desc,chr(10),' '),chr(13),' ') from products  where prod_id=2; 

Output :test first test second test third

Maybe for someone it will be helpful: check the access modifiers for your DTO/Model class' properties, they should be public. In my case during refactoring domain object internals were moved to DTO like this:

// Domain object
public class MyDomainObject {
    public string Name { get; internal set; }
    public string Info { get; internal set; }
}
// DTO
public class MyDomainObjectDto {
    public Name { get; internal set; } // <-- The problem is in setter access modifier (and carelessly performed refactoring).
    public string Info { get; internal set; }
}

DTO is being finely passed to client, but when the time comes to pass the object back to the server it had only empty fields (null/default value). Removing "internal" puts things in order, allowing deserialization mechanizm to write object's properties.

public class MyDomainObjectDto {
    public Name { get; set; }
    public string Info { get; set; }
}

Use a second ArrayList for the 3 strings, not a primitive array. Ie.
private List<List<String>> addresses = new ArrayList<List<String>>();

Then you can have:

ArrayList<String> singleAddress = new ArrayList<String>();
singleAddress.add("17 Fake Street");
singleAddress.add("Phoney town");
singleAddress.add("Makebelieveland");

addresses.add(singleAddress);

(I think some strange things can happen with type erasure here, but I don't think it should matter here)

If you're dead set on using a primitive array, only a minor change is required to get your example to work. As explained in other answers, the size of the array can not be included in the declaration. So changing:

private ArrayList<String[]> addresses = new ArrayList<String[3]>();

to

private ArrayList<String[]> addresses = new ArrayList<String[]>();

will work.

You can use WMI Code creator. I guess you can have a combination of "keys" (processorid,mac and software generated key).

try
{
     ManagementObjectSearcher searcher = 
         new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_Processor"); 

     foreach (ManagementObject queryObj in searcher.Get())
     {
         Console.WriteLine("-----------------------------------");
         Console.WriteLine("Win32_Processor instance");
         Console.WriteLine("-----------------------------------");
         Console.WriteLine("Architecture: {0}", queryObj["Architecture"]);
         Console.WriteLine("Caption: {0}", queryObj["Caption"]);
         Console.WriteLine("Family: {0}", queryObj["Family"]);
         Console.WriteLine("ProcessorId: {0}", queryObj["ProcessorId"]);
     }
}
catch (ManagementException e)
{
    MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}

Retrieving Hardware Identifiers in C# with WMI by Peter Bromberg

I was able to achieve a redirect in react-router-dom using the following

<Route exact path="/" component={() => <Redirect to={{ pathname: '/YourRoute' }} />} />

For my case, I was looking for a way to redirect users whenever they visit the root URL http://myapp.com to somewhere else within the app http://myapp.com/newplace. so the above helped.

Any class that can be serialized (i.e. implements Serializable) should declare that UID and it must be changed whenever anything changes that affects the serialization (additional fields, removed fields, change of field order, ...). The field's value is checked during deserialization and if the value of the serialized object does not equal the value of the class in the current VM, an exception is thrown.

Note that this value is special in that it is serialized with the object even though it is static, for the reasons described above.

    $time_parts=explode(":",$time);

    return $seconds;

function secondToTime($time){

You can cast it to an intptr_t type. It's an int type guaranteed to be big enough to contain a pointer. Use #include <cstdint> to define it.

Here's intuitive understanding of runtime complexity of Euclid's algorithm. The formal proofs are covered in various texts such as Introduction to Algorithms and TAOCP Vol 2.

First think about what if we tried to take gcd of two Fibonacci numbers F(k+1) and F(k). You might quickly observe that Euclid's algorithm iterates on to F(k) and F(k-1). That is, with each iteration we move down one number in Fibonacci series. As Fibonacci numbers are O(Phi ^ k) where Phi is golden ratio, we can see that runtime of GCD was O(log n) where n=max(a, b) and log has base of Phi. Next, we can prove that this would be the worst case by observing that Fibonacci numbers consistently produces pairs where the remainders remains large enough in each iteration and never become zero until you have arrived at the start of the series.

We can make O(log n) where n=max(a, b) bound even more tighter. Assume that b >= a so we can write bound at O(log b). First, observe that GCD(ka, kb) = GCD(a, b). As biggest values of k is gcd(a,c), we can replace b with b/gcd(a,b) in our runtime leading to more tighter bound of O(log b/gcd(a,b)).

You can do a custom namespace of events.

$('span').bind('click.doStuff1',function(){doStuff1();});
$('span').bind('click.doStuff2',function(){doStuff2();});

Then, when you need to trigger them you can choose the order.

$('span').trigger('click.doStuff1').trigger('click.doStuff2');

or

$('span').trigger('click.doStuff2').trigger('click.doStuff1');

Also, just triggering click SHOULD trigger both in the order they were bound... so you can still do

$('span').trigger('click'); 

If you're using django, you can use urlquote:

>>> from django.utils.http import urlquote
>>> urlquote(u"Müller")
u'M%C3%BCller'

Note that changes to Python since this answer was published mean that this is now a legacy wrapper. From the Django 2.1 source code for django.utils.http:

A legacy compatibility wrapper to Python's urllib.parse.quote() function.
(was used for unicode handling on Python 2)

If you don't want to mutate in place, but return a clone with the null/undefined removed, you could use the ES6 reduce function.

// Helper to remove undefined or null properties from an object
function removeEmpty(obj) {
  // Protect against null/undefined object passed in
  return Object.keys(obj || {}).reduce((x, k) => {
    // Check for null or undefined
    if (obj[k] != null) {
      x[k] = obj[k];
    }
    return x;
  }, {});
}

You can easily use .replace() as also previously described. But it is also important to keep in mind that strings are immutable. Hence if you do not assign the change you are making to a variable, then you will not see any change. Let me explain by;

    >>stuff = "bin and small"
    >>stuff.replace('and', ',')
    >>print(stuff)
    "big and small" #no change

To observe the change you want to apply, you can assign same or another variable;

    >>stuff = "big and small"
    >>stuff = stuff.replace("and", ",")   
    >>print(stuff)
    'big, small'

You can solve this by simply adding class to modal-header

<div class="modal-header bg-primary text-white">

In a real world environment it's never a good idea to work solely with time, always use datetime, even better utc, to avoid conflicts like overnight, daylight saving, different timezones between user and server etc.

So I'd recommend this approach:

import datetime as dt

_now = dt.datetime.now()  # or dt.datetime.now(dt.timezone.utc)
_in_5_sec = _now + dt.timedelta(seconds=5)

# get '14:39:57':
_in_5_sec.strftime('%H:%M:%S')

You need to consider the case where the user presses enter in the middle of the text, not just at the end. I'd suggest detecting the enter key in the keyup event, as suggested, and use a regular expression to ensure the value is as you require:

<textarea id="t" rows="4" cols="80"></textarea>
<script type="text/javascript">
    function formatTextArea(textArea) {
        textArea.value = textArea.value.replace(/(^|\r\n|\n)([^*]|$)/g, "$1*$2");
    }

    window.onload = function() {
        var textArea = document.getElementById("t");
        textArea.onkeyup = function(evt) {
            evt = evt || window.event;

            if (evt.keyCode == 13) {
                formatTextArea(this);
            }
        };
    };
</script>

Why it does not work

There is no datetime dtype to be set for read_csv as csv files can only contain strings, integers and floats.

Setting a dtype to datetime will make pandas interpret the datetime as an object, meaning you will end up with a string.

Pandas way of solving this

The pandas.read_csv() function has a keyword argument called parse_dates

Using this you can on the fly convert strings, floats or integers into datetimes using the default date_parser (dateutil.parser.parser)

headers = ['col1', 'col2', 'col3', 'col4']
dtypes = {'col1': 'str', 'col2': 'str', 'col3': 'str', 'col4': 'float'}
parse_dates = ['col1', 'col2']
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes, parse_dates=parse_dates)

This will cause pandas to read col1 and col2 as strings, which they most likely are ("2016-05-05" etc.) and after having read the string, the date_parser for each column will act upon that string and give back whatever that function returns.

Defining your own date parsing function:

The pandas.read_csv() function also has a keyword argument called date_parser

Setting this to a lambda function will make that particular function be used for the parsing of the dates.

GOTCHA WARNING

You have to give it the function, not the execution of the function, thus this is Correct

date_parser = pd.datetools.to_datetime

This is incorrect:

date_parser = pd.datetools.to_datetime()

Pandas 0.22 Update

pd.datetools.to_datetime has been relocated to date_parser = pd.to_datetime

Thanks @stackoverYC

I think it's local to the file you declared offset. Consider every file to be a method itself.

Maybe put the whole thing into a class and then make offset a class variable with @@offset = Point.new(100, 200);?

I made a small library that lets you easily use a throbber without images.

It uses CSS3 but falls back onto JavaScript if the browser doesn't support it.

// First argument is a reference to a container element in which you
// wish to add a throbber to.
// Second argument is the duration in which you want the throbber to
// complete one full circle.
var throbber = throbbage(document.getElementById("container"), 1000);

// Start the throbber.
throbber.play();

// Pause the throbber.
throbber.pause();

Example.

It looks like window.open will take a Data URI as the location parameter.

So you can open it like this from the question: Opening PDF String in new window with javascript:

window.open("data:application/pdf;base64, " + base64EncodedPDF);

Here's an runnable example in plunker, and sample pdf file that's already base64 encoded.

Then on the server, you can convert the byte array to base64 encoding like this:

string fileName = @"C:\TEMP\TEST.pdf";
byte[] pdfByteArray = System.IO.File.ReadAllBytes(fileName);
string base64EncodedPDF = System.Convert.ToBase64String(pdfByteArray);

NOTE: This seems difficult to implement in IE because the URL length is prohibitively small for sending an entire PDF.

I think the confusion is that on my server I had to right click the Task Scheduler Library on left hand side and right click to get the option to enable or disable all tasks history.

Hope this helps

Try:

SELECT strftime("%Y-%d-%m", col_name, 'unixepoch') AS col_name

It will format timestamp in milliseconds to yyyy-mm-dd string.

Flushing the output buffers:

printf("Buffered, will be flushed");
fflush(stdout); // Prints to screen or whatever your standard out is

or

fprintf(fd, "Buffered, will be flushed");
fflush(fd);  //Prints to a file

Can be a very helpful technique. Why would you want to flush an output buffer? Usually when I do it, it's because the code is crashing and I'm trying to debug something. The standard buffer will not print everytime you call printf() it waits until it's full then dumps a bunch at once. So if you're trying to check if you're making it to a function call before a crash, it's helpful to printf something like "got here!", and sometimes the buffer hasn't been flushed before the crash happens and you can't tell how far you've really gotten.

Another time that it's helpful, is in multi-process or multi-thread code. Again, the buffer doesn't always flush on a call to a printf(), so if you want to know the true order of execution of multiple processes you should fflush the buffer after every print.

I make a habit to do it, it saves me a lot of headache in debugging. The only downside I can think of to doing so is that printf() is an expensive operation (which is why it doesn't by default flush the buffer).

As far as flushing the input buffer (stdin), you should not do that. Flushing stdin is undefined behavior according to the C11 standard §7.21.5.2 part 2:

If stream points to an output stream ... the fflush function causes any unwritten data for that stream ... to be written to the file; otherwise, the behavior is undefined.

On some systems, Linux being one as you can see in the man page for fflush(), there's a defined behavior but it's system dependent so your code will not be portable.

Now if you're worried about garbage "stuck" in the input buffer you can use fpurge() on that. See here for more on fflush() and fpurge()

You don't have a validator on the page. Add something like this to show the validation message.

@Html.ValidationMessageFor(model => model.PhoneNumber, "", new { @class = "text-danger" })

another way it to use the millisecond timer:

var uniq = 'id' + (new Date()).getTime();

In my experience, the most friendly way of dealing with this is to have a function that converts a string into a table of values.

There are many splitter functions available on the web, you'll easily find one for whatever if your flavour of SQL.

You can then do...

SELECT * FROM table WHERE id IN (SELECT id FROM split(@list_of_ids))

Or

SELECT * FROM table INNER JOIN (SELECT id FROM split(@list_of_ids)) AS list ON list.id = table.id

(Or similar)

This is for until IE9

<!--[if IE ]>
<style> .someclass{
    text-align: center;
    background: #00ADEF;
    color: #fff;
    visibility:hidden;  // in case of hiding
       }
#someotherclass{
    display: block !important;
    visibility:visible; // in case of visible

}
</style>

This is for after IE9

  @media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {enter your CSS here}

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

This is a complete code for select statements.

SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
    do {
        // Passing values 
        String column1 = c.getString(0);
        String column2 = c.getString(1);
        String column3 = c.getString(2); 
        // Do something Here with values
    } while(c.moveToNext());
}
c.close();
db.close();

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date
  
      Dim wb As Workbook
      Dim dProps As DocumentProperties
      Dim pValue As DocumentProperty
      Dim pDate As DocumentProperty
      Dim sName As String
      Dim sNameDate As String
  
      Dim bDate As Boolean
      Dim bValue As Boolean
      Dim bChanged As Boolean
  
      bDate = True
      bValue = True
  
      bChanged = False
  
  
      Dim sVal As String
      Dim dDate As Date
  
      sName = inData.Address & "_" & inData.Worksheet.Name
      sNameDate = sName & "_dat"
  
      sVal = CStr(inData.Value)
      dDate = Now()
  
      Set wb = inData.Worksheet.Parent
  
      Set dProps = wb.CustomDocumentProperties
  
  On Error Resume Next
  
      Set pValue = dProps.Item(sName)
  
      If Err.Number <> 0 Then
          bValue = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

This is what I found. Adding /usr/local/apache-tomcat-7.0.64/lib/servlet-api.jar in my environment variable as CLASSPATH. OS is iOS.

if using bash: ~/.bash_profile $CLASSPATH=/usr/local/apache-tomcat-7.0.64/lib/servlet-api.jar

if using zsh: ~/.zshrc export CLASSPATH="usr/local/apache-tomcat-7.0.64/lib/servlet-api.jar"

Force it work right now, run source .bash_profile (or .zshrc) or one can restart computer and it works for the current user.

To make a custom "browse button" solution simply try making a hidden browse button, a custom button or element and some Jquery. This way I'm not modifying the actual "browse button" which is dependent on each browser/version. Here's an example.

HTML:

<div id="import" type="file">My Custom Button</div>
<input id="browser" class="hideMe" type="file"></input>

CSS:

#import {
  margin: 0em 0em 0em .2em;
  content: 'Import Settings';
  display: inline-block;
  border: 1px solid;
  border-color: #ddd #bbb #999;
  border-radius: 3px;
  padding: 5px 8px;
  outline: none;
  white-space: nowrap;
  -webkit-user-select: none;
  cursor: pointer;
  font-weight: 700;
  font: bold 12px/1.2 Arial,sans-serif !important;
  /* fallback */
  background-color: #f9f9f9;
  /* Safari 4-5, Chrome 1-9 */
  background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#C2C1C1), to(#2F2727));
}

.hideMe{
    display: none;
}

JS:

$("#import").click(function() {
    $("#browser").trigger("click");
    $('#browser').change(function() {
            alert($("#browser").val());
    });
});

Straight from the designer of Lua himself:

Our main concern with "continue" is that there are several other control structures that (in our view) are more or less as important as "continue" and may even replace it. (E.g., break with labels [as in Java] or even a more generic goto.) "continue" does not seem more special than other control-structure mechanisms, except that it is present in more languages. (Perl actually has two "continue" statements, "next" and "redo". Both are useful.)

The solutions provided to this question are all applicable to targetSdkVersion s of 23 and below. For Android N, i.e. API level 24, and above, however, they do not work and crash with the following Exception:

android.os.FileUriExposedException: file:///storage/emulated/0/... exposed beyond app through Intent.getData()

This is due to the fact that starting from Android 24, the Uri for addressing the downloaded file has changed. For instance, an installation file named appName.apk stored on the primary external filesystem of the app with package name com.example.test would be as

file:///storage/emulated/0/Android/data/com.example.test/files/appName.apk

for API 23 and below, whereas something like

content://com.example.test.authorityStr/pathName/Android/data/com.example.test/files/appName.apk

for API 24 and above.

More details on this can be found here and I am not going to go through it.

To answer the question for targetSdkVersion of 24 and above, one has to follow these steps: Add the following to the AndroidManifest.xml:

<application
        android:allowBackup="true"
        android:label="@string/app_name">
        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}.authorityStr"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/paths"/>
        </provider>
</application>

2. Add the following paths.xml file to the xml folder on res in src, main:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path
        name="pathName"
        path="pathValue"/>
</paths>

The pathName is that shown in the exemplary content uri example above and pathValue is the actual path on the system. It would be a good idea to put a "." (without quotes) for pathValue in the above if you do not want to add any extra subdirectory.

3. Write the following code to install the apk with the name appName.apk on the primary external filesystem:

   File directory = context.getExternalFilesDir(null);
   File file = new File(directory, fileName);
   Uri fileUri = Uri.fromFile(file);
   if (Build.VERSION.SDK_INT >= 24) {
       fileUri = FileProvider.getUriForFile(context, context.getPackageName(),
               file);
   }
   Intent intent = new Intent(Intent.ACTION_VIEW, fileUri);
   intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
   intent.setDataAndType(fileUri, "application/vnd.android" + ".package-archive");
   intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
   intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
   context.startActivity(intent);
   activity.finish();
   

No permission is also necessary when writing to your own app's private directory on the external filesystem.

I have written an AutoUpdate library here in which I have used the above.

I just hit this after doing a fresh install of DOCKER from the main docs. The problem for me was that immediately after the install, the service is not running.

These commands will help you to make sure docker is up and running for your run command to find it:

$ sudo service --status-all 
$ sudo service docker start
$ sudo service docker start

In a GET request, you pass parameters as part of the query string.

string url = "http://somesite.com?var=12345";

A perfect example of this is:

$ npm install typescript --save-dev

In this case, you'd want to have Typescript (a javascript-parseable coding language) available for development, but once the app is deployed, it is no longer necessary, as all of the code has been transpiled to javascript. As such, it would make no sense to include it in the published app. Indeed, it would only take up space and increase download times.

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state
  

For varchars, you may need to do something like this:

select convert(varchar(25), NULL) as abc_column into xyz_table

If you try

select '' as abc_column into xyz_table

you may get errors related to truncation, or an issue with null values, once you populate.

Bootstrap 4:

$('#myModal').on('hidden.bs.modal', function (e) {
   // call your method
})

hide.bs.modal: This event is fired immediately when the hide instance method has been called.

hidden.bs.modal: This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).

if you have zsh installed you can also update ~/.zprofile with

if [[ -z "$LC_ALL" ]]; then
  export LC_ALL='en_US.UTF-8'
fi

and check the output using the locale cmd as show above

? locale                                                                                                                                           
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL="en_US.UTF-8"

    byte[] buf;  // byte array
    Stream stream=Page.Request.InputStream;  //initialise new stream
    buf = new byte[stream.Length];  //declare arraysize
    stream.Read(buf, 0, buf.Length); // read from stream to byte array

You CAN do this if you are willing to "frig" it a little by making a variable of the static class and assigning it to null. However, this method would not be available to static calls on the class, so not sure how much use it would be:

Console myConsole = null;
myConsole.WriteBlueLine("my blue line");

public static class Helpers {
    public static void WriteBlueLine(this Console c, string text)
    {
        Console.ForegroundColor = ConsoleColor.Blue;
        Console.WriteLine(text);
        Console.ResetColor();
    }
}

CellType cell = row.getCell(j).getCellTypeEnum();

switch(cell) {
    case NUMERIC:
        intVal = row.getCell(j).getNumericCellValue();
        System.out.print(intVal);
        break;
    case STRING:
        stringVal = row.getCell(j).getStringCellValue();
        System.out.print(stringVal);
        break;
}

This match 6 or more any chars but newline:

/^.{6,}$/

Try setting your font from the menu and then typing

:set guifont?

This should display to you the string that Vim has set this option to. You'll need to escape any spaces.

The same as @Nix with a small change to be strongly typed:

If you don't want to query for it just create an entity, and then delete it.

                Customer customer = new Customer () { Id = id };
                context.Customers.Attach(customer);
                context.Customers.DeleteObject(customer);
                context.SaveChanges();

Not sure if this will satisfy all, but I found a simple workaround that fixed the problem for me. Move all your referenced cells/formulas to a different sheet so that you aren't referencing any cells in the sheet that has the table to be sorted. If you do this, you can sort away!

Simplest solution: The Oracle client is not installed on the remote server where the SSIS package is being executed.

Slightly less simple solution: The Oracle client is installed on the remote server, but in the wrong bit-count for the SSIS installation. For example, if the 64-bit Oracle client is installed but SSIS is being executed with the 32-bit dtexec executable, SSIS will not be able to find the Oracle client. The solution in this case would be to install the 32-bit Oracle client side-by-side with the 64-bit client.

Replace this

 <button type="button" value=" Send" class="btn btn-success" type="submit" id="submit">

with

<button  value=" Send" class="btn btn-success" type="submit" id="submit">

public static void ClearLine(int lines = 1)
{
    for (int i = 1; i <= lines; i++)
    {
        Console.SetCursorPosition(0, Console.CursorTop - 1);
        Console.Write(new string(' ', Console.WindowWidth));
        Console.SetCursorPosition(0, Console.CursorTop - 1);
    }
}

This is how I solved the issue.

Copy and run these commands

ng --version
npm install --save-dev @angular/cli@latest
ng --version

Principled Design of the Modern Web Architecture by Roy T. Fielding and Richard N. Taylor, i.e. sequence of works from all REST terminology came from, contains definition of client-server interaction:

All REST interactions are stateless. That is, each request contains all of the information necessary for a connector to understand the request, independent of any requests that may have preceded it.

This restriction accomplishes four functions, 1st and 3rd are important in this particular case:

• 1st: it removes any need for the connectors to retain application state between requests, thus reducing consumption of physical resources and improving scalability;
• 3rd: it allows an intermediary to view and understand a request in isolation, which may be necessary when services are dynamically rearranged;

And now lets go back to your security case. Every single request should contains all required information, and authorization/authentication is not an exception. How to achieve this? Literally send all required information over wires with every request.

One of examples how to archeive this is hash-based message authentication code or HMAC. In practice this means adding a hash code of current message to every request. Hash code calculated by cryptographic hash function in combination with a secret cryptographic key. Cryptographic hash function is either predefined or part of code-on-demand REST conception (for example JavaScript). Secret cryptographic key should be provided by server to client as resource, and client uses it to calculate hash code for every request.

There are a lot of examples of HMAC implementations, but I'd like you to pay attention to the following three:

• Authenticating REST Requests for Amazon Simple Storage Service (Amazon S3)
• Answer by Mauriceless on quiestion: "How to implement HMAC Authentication in a RESTful WCF API"
• crypto-js: JavaScript implementations of standard and secure cryptographic algorithms

How it works in practice

If client knows the secret key, then it's ready to operate with resources. Otherwise he will be temporarily redirected (status code 307 Temporary Redirect) to authorize and to get secret key, and then redirected back to the original resource. In this case there is no need to know beforehand (i.e. hardcode somewhere) what the URL to authorize the client is, and it possible to adjust this schema with time.

Hope this will helps you to find the proper solution!

This solution works only if you create in Xcode 7 the directory "10.0" and you have a mistake in your sentence:

ln -s /Applications/Xcode_8.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0 \(14A345\) /Applications/Xcode_7.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0

The difference between those will depend largely on what browser you are currently referring to. Each one implements these properties differently, or not at all. Quirksmode has great documentation regarding browser differences in regards to W3C standards like the DOM and JavaScript Events.

To make a bash script that will cd to a select directory :

Create the script file

#!/bin/sh
# file : /scripts/cdjava
#
cd /home/askgelal/projects/java

Then create an alias in your startup file.

#!/bin/sh
# file /scripts/mastercode.sh
#
alias cdjava='. /scripts/cdjava'

• I created a startup file where I dump all my aliases and custom functions.
• Then I source this file into my .bashrc to have it set on each boot.

For example, create a master aliases/functions file: /scripts/mastercode.sh
(Put the alias in this file.)

Then at the end of your .bashrc file:

source /scripts/mastercode.sh

Now its easy to cd to your java directory, just type cdjava and you are there.

Normally i use a class for this:

public class ClassName
{
    public string Col1 { get; set; }
    public int Col2 { get; set; }
}

Now you can use a loop to fill a list and ToArray if you really need an array:

ClassName[] allRecords = null;
string sql = @"SELECT col1,col2
               FROM  some table";
using (var command = new SqlCommand(sql, con))
{
    con.Open();
    using (var reader = command.ExecuteReader())
    {
        var list = new List<ClassName>();
        while (reader.Read())
            list.Add(new ClassName { Col1 = reader.GetString(0), Col2 = reader.GetInt32(1) });
        allRecords = list.ToArray();
    }
}

Note that i've presumed that the first column is a string and the second an integer. Just to demonstrate that C# is typesafe and how you use the DataReader.GetXY methods.

You can use str() to cast it, or formatters:

"ME%d.txt" % (num,)

You would never want to run that, but you may want to source it.

. ~/.bash_profile
source ~/.bash_profile

both should work. But this is an odd request, because that file should be sourced automatically when you start bash, unless you're explicitly starting it non-interactively. From the man page:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

I had the same problem using

this.router.url

I get the current route with query params. A workaround I did was using this instead:

this.router.url.split('?')[0]

Not a really nice solution, but helpful.

function sort(data, orderBy) {
        orderBy = Array.isArray(orderBy) ? orderBy : [orderBy];
        return data.sort((a, b) => {
            for (let i = 0, size = orderBy.length; i < size; i++) {
                const key = Object.keys(orderBy[i])[0],
                    o = orderBy[i][key],
                    valueA = a[key],
                    valueB = b[key];

Try like this: server.bind(("0.0.0.0", 6677))

If you are using DataGrip you can do the following:

1. Enter your SELECT statement SELECT * FROM <your_table>;
2. Put your cursor over * and press Alt+Enter
3. You will get pop up menu with Expand column list option
4. Click on it and it will convert * with full list of columns
5. Now you can remove columns that you don't need

Here is a link for an example on how to do it.

Are you looking for a 2 column CSS layout?

If so, have a look at the instructions, it's pretty straightforward for starting.

When you want to create interval store promise to variable:

var p = $interval(function() { ... },1000);

And when you want to stop / clear the interval simply use:

$interval.cancel(p);

You add this you want to launch activity android:exported="true" in manifest file like

 <activity
      android:name=".activities.activity.MainActivity"
      android:windowSoftInputMode="adjustPan"
      android:exported="true"/>
  <activity

Open java file of this activity and right click then click on Run 'main Activity'

OR

Open java file of this activity and press Ctrl+Shift+F10.

Try the following and see if it works:

<video width="400" height="300" preload controls>
  <source src="video.mp4" type="video/mp4" />
  Your browser does not support the video tag.
</video>

I just experienced the same problem using the virtual environment. For me installing the package using python from the venv worked:
.\venv\environment\Scripts\python.exe -m pip install flask-sqlalchemy

If you have to load a lot of data into tables on a regular basis, check out SQL Loader or external tables. Should be much faster than individual Inserts.

Make a list of all letters in the US English Alphabet, skipping a & b. "CDEFGHIJKLMNOPQRSTUVWXYZ". Open each of those drives with CreateFile e.g. CreateFile("\\.\C:"). If it does not return INVALID_HANDLE_VALUE then you got a 'good' drive. Next take that handle and run it through DeviceIoControl to get the Disk #. See my related answer for more details.

I had the same problem, fixed by replacing R with com.example.appname.R obviously put your package reference in there instead. Or just add this line to your file:

import com.your.package.R

Or even better, try removing this line from your code if exists:

import android.support.compat.R

Add reference of service in your service or copy dll.

I just learned from a website:

Get-ChildItem *.txt | ForEach-Object { (get-Content $_) | Where-Object {(1) -notcontains $_.ReadCount } | Set-Content -path $_ }

Or you can use the aliases to make it short, like:

gci *.txt | % { (gc $_) | ? { (1) -notcontains $_.ReadCount } | sc -path $_ }

Click handlers on anchor tags are a special case in jQuery.

I think you might be getting confused between the anchor's onclick event (known by the browser) and the click event of the jQuery object which wraps the DOM's notion of the anchor tag.

You can download the jQuery 1.3.2 source here.

The relevant sections of the source are lines 2643-2645 (I have split this out to multiple lines to make it easier to comprehend):

// Handle triggering native .onfoo handlers (and on links since we don't call .click() for links)
if (
     (!elem[type] || (jQuery.nodeName(elem, 'a') && type == "click")) && 
       elem["on"+type] && 
       elem["on"+type].apply( elem, data ) === false
   )
     event.result = false;

Try this actually:

$('#textareaID').bind('input propertychange', function() {

      $("#yourBtnID").hide();

      if(this.value.length){
        $("#yourBtnID").show();
      }
});

DEMO

That works for any changes you make, typing, cutting, pasting.

Try this:

var src = DateTime.Now;
var hm = new DateTime(src.Year, src.Month, src.Day, src.Hour, src.Minute, 0);

Here is obscure solution: define macro function:

#define Z(x) \
        (x==0 ? 'A' : \
        (x==1 ? 'B' : \
        (x==2 ? 'C' : '\0')))

char x[] = { Z(0), Z(1), Z(2) };

I had the same problem. I changed the Version of Assembly in AssemblyInfo.cs in the Properties Folder. But, I don't have any idea why this problem happened. Maybe the compiler doesn't understand that this dll is newer, just changing the version of Assembly.

(The first options are of course mentioned in other answers, here the goal is to show that glob uses os.scandir internally, and provide a direct answer with this).

Using glob

As explained before, with Python 3.5+, it's easy:

import glob
for f in glob.glob('d:/temp/**/*', recursive=True):
    print(f)

#d:\temp\New folder
#d:\temp\New Text Document - Copy.txt
#d:\temp\New folder\New Text Document - Copy.txt
#d:\temp\New folder\New Text Document.txt

Using pathlib

from pathlib import Path
for f in Path('d:/temp').glob('**/*'):
    print(f)

Using os.scandir

os.scandir is what glob does internally. So here is how to do it directly, with a use of yield:

def listpath(path):
    for f in os.scandir(path):
        f2 = os.path.join(path, f)
        if os.path.isdir(f):
            yield f2
            yield from listpath(f2)
        else:
            yield f2

for f in listpath('d:\\temp'):
    print(f)

you can use

<a href="\\computername\folder">Open folder</a>

in Internet Explorer

This is simple code, so if you are new you should understand it easily enough.

    mylist = ["x", 3, "b"]
    for items in mylist:
        print(items)

It prints all of them without quotes, like you wanted.

If you need the line number for more than just the formatted stack trace you get from Exception.StackTrace, you can use the StackTrace class:

try
{
    throw new Exception();
}
catch (Exception ex)
{
    // Get stack trace for the exception with source file information
    var st = new StackTrace(ex, true);
    // Get the top stack frame
    var frame = st.GetFrame(0);
    // Get the line number from the stack frame
    var line = frame.GetFileLineNumber();
}

Note that this will only work if there is a pdb file available for the assembly.

you can use this simple way

<select onchange="location = this.value;">
                <option value="/finished">Finished</option>
                <option value="/break">Break</option>
                <option value="/issue">Issues</option>
                <option value="/downtime">Downtime</option>
</select>

will redirect to route url you can direct to .html page or direct to some link just change value in option.

In my case there was another directory within my workspace, having the same jar file as the one in my project. I hadn't created that directory or anything in it. It was created by Eclipse I believe. I just erased that directory and it just runs ok.

The form element has an autocomplete attribute that you can set to off. As of the CSS the !important directive after a property keeps it from being overriden:

background-color: white !important;

Only IE6 doesn't understand it.

If I misunderstood you, there's also the outline property that you could find useful.

Another posibility is using intent.getAction:

In Service:

public class SampleService inherits Service{
    static final String ACTION_START = "com.yourcompany.yourapp.SampleService.ACTION_START";
    static final String ACTION_DO_SOMETHING_1 = "com.yourcompany.yourapp.SampleService.DO_SOMETHING_1";
    static final String ACTION_DO_SOMETHING_2 = "com.yourcompany.yourapp.SampleService.DO_SOMETHING_2";
    static final String ACTION_STOP_SERVICE = "com.yourcompany.yourapp.SampleService.STOP_SERVICE";

    @Override

If you frequently use a large number of exceptions, you can pre-define a tuple, so you don't have to re-type them many times.

#This example code is a technique I use in a library that connects with websites to gather data

ConnectErrs  = (URLError, SSLError, SocketTimeoutError, BadStatusLine, ConnectionResetError)

def connect(url, data):
    #do connection and return some data
    return(received_data)

def some_function(var_a, var_b, ...):
    try: o = connect(url, data)
    except ConnectErrs as e:
        #do the recovery stuff
    blah #do normal stuff you would do if no exception occurred

NOTES:

1. If you, also, need to catch other exceptions than those in the pre-defined tuple, you will need to define another except block.

2. If you just cannot tolerate a global variable, define it in main() and pass it around where needed...

update mytable
set myfield = replace (myfield, '  ',  ' ')
where charindex('  ', myfield) > 0 

Replace will work on all the double spaces, no need to put in multiple replaces. This is the set-based solution.

With Hibernate 5.2, you can now force the UTC time zone using the following configuration property:

There's a Windows Explorer extension made by the dude who makes tools for SVN that will at least open a command prompt window.

Take a look at onBeforeUnload.

It wont force someone to stay but it will prompt them asking them whether they really want to leave, which is probably the best cross browser solution you can manage. (Similar to this site if you attempt to leave mid-answer.)

<script language="JavaScript">
    window.onbeforeunload = confirmExit;
    function confirmExit() {
        return "You have attempted to leave this page. Are you sure?";
    }
</script>

Edit: Most browsers no longer allow a custom message for onbeforeunload.

See this bug report from the 18th of February, 2016.

onbeforeunload dialogs are used for two things on the Modern Web:
1. Preventing users from inadvertently losing data.
2. Scamming users.

In an attempt to restrict their use for the latter while not stopping the former, we are going to not display the string provided by the webpage. Instead, we are going to use a generic string.

Firefox already does this[...]

Modify your estimated population function to take a growth argument of type float. Then you can call the growthRate function with your birthRate and deathRate and use the return value as the input for grown into estimatedPopulation.

float growthRate (float birthRate, float deathRate)     
{    
    return ((birthRate) - (deathRate));    
}

int estimatedPopulation (int currentPopulation, float growth)
{
    return ((currentPopulation) + (currentPopulation) * (growth / 100);
}

// main.cpp
int currentPopulation = 100;
int births = 50;
int deaths = 25;
int population = estimatedPopulation(currentPopulation, growthRate(births, deaths));

AppCompat doesn't do that for dialogs (not yet at least)

EDIT: it does now. make sure to use android.support.v7.app.AlertDialog

For those that implemented react js in some part of the website and encounter this issue. Just add a condition to check if the element exist on that page before you render the react component.

<div id="element"></div>

...

const someElement = document.getElementById("element")
    
if(someElement) {
  ReactDOM.render(<Yourcomponent />, someElement)
}

OK why so complex!

package main

import (
    "fmt"
    "math/rand"
    "time"
)

func main() {
    rand.Seed( time.Now().UnixNano())
    var bytes int

    for i:= 0 ; i < 10 ; i++{ 
        bytes = rand.Intn(6)+1
        fmt.Println(bytes)
        }
    //fmt.Println(time.Now().UnixNano())
}

This is based off the dystroy's code but fitted for my needs.

It's die six (rands ints 1 =< i =< 6)

func randomInt (min int , max int  ) int {
    var bytes int
    bytes = min + rand.Intn(max)
    return int(bytes)
}

The function above is the exactly same thing.

I hope this information was of use.

If you want to do this using regex, you could simply use a non-capturing group, to get the word "world" and then grab everything after, like so

(?:world).*

It is easier to compare dates using the java.util.Calendar. Here is what you might do:

Calendar toDate = Calendar.getInstance();
Calendar nowDate = Calendar.getInstance();
toDate.set(<set-year>,<set-month>,<set-day>);  
if(!toDate.before(nowDate)) {
    //display your report
} else {
    // don't display the report
}

I think that depth first search solves it. If an unexplored edge leads to a node visited before, then the graph contains a cycle. This condition also makes it O(n), since you can explore maximum n edges without setting it to true or being left with no unexplored edges.

Here's a concise method to cut the first X characters using cut(1). This example removes the first 4 characters by cutting a substring starting with 5th character.

echo "$pid" | cut -c 5-

You can also use:

@if(string.IsNullOrEmpty(Model.CreatorFullName))
{
...your code...
}

No need for a variable in the code

Create a Map or a Set, and using "on connection" event set to it each connected socket, in reverse "once disconnect" event delete that socket from the Map we created earlier

import * as Server from 'socket.io';

const io = Server();
io.listen(3000);

const connections = new Set();

io.on('connection', function (s) {

  connections.add(s);

  s.once('disconnect', function () {
    connections.delete(s);
  });

});

R has a number of (undocumented) convenience functions for converting factors:

• as.character.factor
• as.data.frame.factor
• as.Date.factor
• as.list.factor
• as.vector.factor
• ...

But annoyingly, there is nothing to handle the factor -> numeric conversion. As an extension of Joshua Ulrich's answer, I would suggest to overcome this omission with the definition of your own idiomatic function:

as.numeric.factor <- function(x) {as.numeric(levels(x))[x]}

that you can store at the beginning of your script, or even better in your .Rprofile file.

This option was introduced in order to remove the need to deploy very large PIAs (Primary Interop Assemblies) for interop.

It simply embeds the managed bridging code used that allows you to talk to unmanaged assemblies, but instead of embedding it all it only creates the stuff you actually use in code.

Read more in Scott Hanselman's blog post about it and other VS improvements here.

As for whether it is advised or not, I'm not sure as I don't need to use this feature. A quick web search yields a few leads:

• Check your Embed Interop Types flag when doing Visual Studio extensibility work
• The Pain of deploying Primary Interop Assemblies

The only risk of turning them all to false is more deployment concerns with PIA files and a larger deployment if some of those files are large.

It may be more useful to use a http client library like such as this

There are more things like access denied , document moved etc to handle when dealing with http.

I think this should satisfy your need:

import pandas as pd

# Read the excel sheet to pandas dataframe
df = pd.read_excel("PATH\FileName.xlsx", sheetname=0)

In my case, I was creating the repository from source code already in my pc and that error appeared. I deleted the .git folder and did everything again and it worked :)

To use full power of scp you need to go through next steps:

1. Public key authorisation
2. Create ssh aliases

Then, for example if you have this ~/.ssh/config:

Host test
    User testuser
    HostName test-site.com
    Port 22022

Host prod
    User produser
    HostName production-site.com
    Port 22022

you'll save yourself from password entry and simplify scp syntax like this:

scp -r prod:/path/foo /home/user/Desktop   # copy to local
scp -r prod:/path/foo test:/tmp            # copy from remote prod to remote test

More over, you will be able to use remote path-completion:

scp test:/var/log/  # press tab twice
Display all 151 possibilities? (y or n)

Update:

For enabling remote bash-completion you need to have bash-shell on both <source> and <target> hosts, and properly working bash-completion. For more information see related questions:

How to enable autocompletion for remote paths when using scp?

What you're looking for is date --date='06/12/2012 07:21:22' +"%s". Keep in mind that this assumes you're using GNU coreutils, as both --date and the %s format string are GNU extensions. POSIX doesn't specify either of those, so there is no portable way of making such conversion even on POSIX compliant systems.

Consult the appropriate manual page for other versions of date.

Note: bash --date and -d option expects the date in US or ISO8601 format, i.e. mm/dd/yyyy or yyyy-mm-dd, not in UK, EU, or any other format.

As soon as a WHEN statement is true the break is implicit.

You will have to concider which WHEN Expression is the most likely to happen. If you put that WHEN at the end of a long list of WHEN statements, your sql is likely to be slower. So put it up front as the first.

More information here: break in case statement in T-SQL

WITH    q AS 
        (
        SELECT  *
        FROM    mytable
        WHERE   ParentID IS NULL -- this condition defines the ultimate ancestors in your chain, change it as appropriate
        UNION ALL
        SELECT  m.*
        FROM    mytable m
        JOIN    q
        ON      m.parentID = q.PersonID
        )
SELECT  *
FROM    q

By adding the ordering condition, you can preserve the tree order:

WITH    q AS 
        (
        SELECT  m.*, CAST(ROW_NUMBER() OVER (ORDER BY m.PersonId) AS VARCHAR(MAX)) COLLATE Latin1_General_BIN AS bc
        FROM    mytable m
        WHERE   ParentID IS NULL
        UNION ALL
        SELECT  m.*,  q.bc + '.' + CAST(ROW_NUMBER() OVER (PARTITION BY m.ParentID ORDER BY m.PersonID) AS VARCHAR(MAX)) COLLATE Latin1_General_BIN
        FROM    mytable m
        JOIN    q
        ON      m.parentID = q.PersonID
        )
SELECT  *
FROM    q
ORDER BY
        bc

By changing the ORDER BY condition you can change the ordering of the siblings.

I'm obviosly not a very good R coder, but if you wanted to do this with ggplot2:

data<- rbind(c(480, 780, 431, 295, 670, 360,  190),
             c(720, 350, 377, 255, 340, 615,  345),
             c(460, 480, 179, 560,  60, 735, 1260),
             c(220, 240, 876, 789, 820, 100,   75))

a <- cbind(data[, 1], 1, c(1:4))
b <- cbind(data[, 2], 2, c(1:4))
c <- cbind(data[, 3], 3, c(1:4))
d <- cbind(data[, 4], 4, c(1:4))
e <- cbind(data[, 5], 5, c(1:4))
f <- cbind(data[, 6], 6, c(1:4))
g <- cbind(data[, 7], 7, c(1:4))

data           <- as.data.frame(rbind(a, b, c, d, e, f, g))
colnames(data) <-c("Time", "Type", "Group")
data$Type      <- factor(data$Type, labels = c("A", "B", "C", "D", "E", "F", "G"))

library(ggplot2)

ggplot(data = data, aes(x = Type, y = Time, fill = Group)) + 
       geom_bar(stat = "identity") +
       opts(legend.position = "none")

You must use the global declaration when you wish to alter the value assigned to a global variable.

You do not need it to read from a global variable. Note that calling a method on an object (even if it alters the data within that object) does not alter the value of the variable holding that object (absent reflective magic).

objList.Select(o=>o.typeId).Distinct()

In case you don't want to get mad with spaces in arguments and want to use variables try this:

objshell.run "cscript ""99 Writelog.vbs"" /r:" &  r & " /f:""" & wscript.scriptname & """ /c:""" & c & ""

where

r=123
c="Whatever comment you like"

According to the closure definition:

A "closure" is an expression (typically a function) that can have free variables together with an environment that binds those variables (that "closes" the expression).

You are using closure if you define a function which use a variable which is defined outside of the function. (we call the variable a free variable).
They all use closure(even in the 1st example).

Use array_unique().

Example:

$array = array(1, 2, 2, 3);
$array = array_unique($array); // Array is now (1, 2, 3)

Your can use DataSourceBuilder for this purpose.

@Primary
@Bean(name = "dataSource")
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource dataSource(Environment env) {
    final String datasourceUsername = env.getRequiredProperty("spring.datasource.username");
    final String datasourcePassword = env.getRequiredProperty("spring.datasource.password");
    final String datasourceUrl = env.getRequiredProperty("spring.datasource.url");
    final String datasourceDriver = env.getRequiredProperty("spring.datasource.driver-class-name");
    return DataSourceBuilder
            .create()
            .username(datasourceUsername)
            .password(datasourcePassword)
            .url(datasourceUrl)
            .driverClassName(datasourceDriver)
            .build();
}

Basically yes, JSON is just a javascript literal representation of your value so what you said is correct.

You can find a pretty clear and good explanation of JSON notation on http://json.org/

Simplest way:

public static long getDifferenceDays(Date d1, Date d2) {
    long diff = d2.getTime() - d1.getTime();
    return TimeUnit.DAYS.convert(diff, TimeUnit.MILLISECONDS);
}

Typically you could use mongoose validation but since you need an async result (db query for existing names) and validators don't support promises (from what I can tell), you will need to create your own function and pass a callback. Here is an example:

var mongoose = require('mongoose'),
    Schema = mongoose.Schema,
    ObjectId = Schema.ObjectId;

mongoose.connect('mongodb://localhost/testDB');

var UserSchema = new Schema({
    name: {type:String}
});

var UserModel = mongoose.model('UserModel',UserSchema);

function updateUser(user,cb){
    UserModel.find({name : user.name}, function (err, docs) {
        if (docs.length){
            cb('Name exists already',null);
        }else{
            user.save(function(err){
                cb(err,user);
            });
        }
    });
}

UserModel.findById(req.param('sid'),function(err,existingUser){
   if (!err && existingUser){
       existingUser.name = 'Kevin';
       updateUser(existingUser,function(err2,user){
           if (err2 || !user){
               console.log('error updated user: ',err2);
           }else{
               console.log('user updated: ',user);
           }

       });
   } 
});

UPDATE: A better way

The pre hook seems to be a more natural place to stop the save:

UserSchema.pre('save', function (next) {
    var self = this;
    UserModel.find({name : self.name}, function (err, docs) {
        if (!docs.length){
            next();
        }else{                
            console.log('user exists: ',self.name);
            next(new Error("User exists!"));
        }
    });
}) ;

UPDATE 2: Async custom validators

It looks like mongoose supports async custom validators now so that would probably be the natural solution:

    var userSchema = new Schema({
      name: {
        type: String,
        validate: {
          validator: function(v, cb) {
            User.find({name: v}, function(err,docs){
               cb(docs.length == 0);
            });
          },
          message: 'User already exists!'
        }
      }
    });

this fails:

 DECLARE @vPortalUID NVARCHAR(32)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS uniqueidentifier)
 PRINT @nPortalUID

this works

 DECLARE @vPortalUID NVARCHAR(36)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS UNIQUEIDENTIFIER)
 PRINT @nPortalUID

the difference is NVARCHAR(36), your input parameter is too small!

It depends on whether you want an int or float field. Here's what the two would look like:

<input type="number" name="int-field" id="int-field" placeholder="positive int" min="1" step="1">
<input type="number" name="float-field" id="float-field" placeholder="positive float" min="0">

The int field has the correct validation attached to it, since its min is 1. The float field accepts 0, however; to deal with this, you can add one more constraint validator:

function checkIsPositive(e) {
  const value = parseFloat(e.target.value);
  if (e.target.value === "" || value > 0) {
    e.target.setCustomValidity("");
  } else {
    e.target.setCustomValidity("Please select a value that is greater than 0.");
  }
}

document.getElementById("float-field").addEventListener("input", checkIsPositive, false);

JSFiddle here.

Note that none of these solutions completely prevent the user from trying to type in invalid input, but you can call checkValidity or reportValidity to figure out whether the user has typed in valid input.

Of course, you should still have server-side validation because the user can always ignore client-side validation.

Try this to get an array of attribute name => attribute value(s):

global $product;

$formatted_attributes = array();

$attributes = $product->get_attributes();

foreach($attributes as $attr=>$attr_deets){

    $attribute_label = wc_attribute_label($attr);

    if ( isset( $attributes[ $attr ] ) || isset( $attributes[ 'pa_' . $attr ] ) ) {

        $attribute = isset( $attributes[ $attr ] ) ? $attributes[ $attr ] : $attributes[ 'pa_' . $attr ];

        if ( $attribute['is_taxonomy'] ) {

            $formatted_attributes[$attribute_label] = implode( ', ', wc_get_product_terms( $product->id, $attribute['name'], array( 'fields' => 'names' ) ) );

        } else {

            $formatted_attributes[$attribute_label] = $attribute['value'];
        }

    }
}

//print_r($formatted_attributes);

return $formatted_attributes;

It's little inefficient but does the trick.

if you load up the XMLDoc I'm pretty sure the .ToString() function posses an overload for this.

But is this for debugging? The reason that it is sent like that is to take up less space (i.e stripping unneccessary whitespace from the XML).

Since @KiritModi 's answer is from 2015, this is the Swift 3.0's version:

func resizeImage(image: UIImage, targetSize: CGSize) -> UIImage {
    let size = image.size

    let widthRatio  = targetSize.width  / image.size.width
    let heightRatio = targetSize.height / image.size.height

    // Figure out what our orientation is, and use that to form the rectangle
    var newSize: CGSize
    if(widthRatio > heightRatio) {
        newSize = CGSize(width: size.width * heightRatio, height: size.height * heightRatio)
    } else {
        newSize = CGSize(width: size.width * widthRatio,  height: size.height * widthRatio)
    }

    // This is the rect that we've calculated out and this is what is actually used below
    let rect = CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height)

    // Actually do the resizing to the rect using the ImageContext stuff
    UIGraphicsBeginImageContextWithOptions(newSize, false, 1.0)
    image.draw(in: rect)
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return newImage!
}

I post the below solution here because after some searching this is where I landed, so other may too. I was trying to use EF 6 to call a stored procedure, but had a similar error because the stored procedure had a linked server being utilized.

The operation could not be performed because OLE DB provider _ for linked server _ was unable to begin a distributed transaction

The partner transaction manager has disabled its support for remote/network transactions*

Jumping over to SQL Client did fix my issue, which also confirmed for me that it was an EF thing.

var connection = new System.Data.SqlClient.SqlConnection(connectionString);    
var cmd = connection.CreateCommand();
cmd.CommandText = "exec [SomeDB].[dbo].[SomeStoredProcedure]";

connection.Open();
var result = cmd.ExecuteNonQuery();

That code can be shortened, but I think that version is slightly more convenient for debugging and stepping through.

I don't believe that Sql Client is necessarily a preferred choice, but I felt this was at least worth sharing if anyone else having similar problems gets landed here by google.

The above Code is C#, but the concept of trying to switch over to Sql Client still applies. At the very least it will be diagnostic to attempt to do so.

Try this

for %i in (javaw.exe) do @echo. %~$PATH:i

?legend will tell you:

Arguments

x, y
the x and y co-ordinates to be used to position the legend. They can be specified by keyword or in any way which is accepted by xy.coords: See ‘Details’.

Details:

Arguments x, y, legend are interpreted in a non-standard way to allow the coordinates to be specified via one or two arguments. If legend is missing and y is not numeric, it is assumed that the second argument is intended to be legend and that the first argument specifies the coordinates.

The coordinates can be specified in any way which is accepted by xy.coords. If this gives the coordinates of one point, it is used as the top-left coordinate of the rectangle containing the legend. If it gives the coordinates of two points, these specify opposite corners of the rectangle (either pair of corners, in any order).

The location may also be specified by setting x to a single keyword from the list bottomright, bottom, bottomleft, left, topleft, top, topright, right and center. This places the legend on the inside of the plot frame at the given location. Partial argument matching is used. The optional inset argument specifies how far the legend is inset from the plot margins. If a single value is given, it is used for both margins; if two values are given, the first is used for x- distance, the second for y-distance.

The query execution happens on all get methods like

$this->db->get('table_name');
$this->db->get_where('table_name',$array);

While last_query contains the last query which was run

$this->db->last_query();

If you want to get query string without execution you will have to do this. Go to system/database/DB_active_rec.php Remove public or protected keyword from these functions

public function _compile_select($select_override = FALSE)
public function _reset_select()

Now you can write query and get it in a variable

$this->db->select('trans_id');
$this->db->from('myTable');
$this->db->where('code','B');
$subQuery = $this->db->_compile_select();

Now reset query so if you want to write another query the object will be cleared.

$this->db->_reset_select();

And the thing is done. Cheers!!! Note : While using this way you must use

$this->db->from('myTable')

instead of

$this->db->get('myTable')

which runs the query.

Take a look at this example

If you came here from Google, trying to find where your previously created virtualenv installation ended up, and why there is no command to find it, here's the low-down.

The design of virtualenv has a fundamental flaw of not being able to keep track of it's own created environments. Someone was not quite in their right mind when they created virtualenv without having a rudimentary way to keep track of already created environments, and certainly not fit for a time and age when most pip requirements require multi-giga-byte installations, which should certainly not go into some obscure .virtualenvs sub-directory of your ~/home.

IMO, the created virtualenv directory should be created in $CWD and a file called ~/.virtualenv (in home) should keep track of the name and path of that creation. Which is a darn good reason to use Conda/Miniconda3 instead, which does seem to keep good track of this.

As answered here, the only way to keep track of this, is to install yet another package called virtualenvwrapper. If you don't do that, you will have to search for the created directory by yourself. Clearly, if you don't remember the name or the location it was created with/at, you will most likely never find your virtual environment again...

One try to remedy the situation in windows, is by putting the following functions into your powershell profile:

# wrap virtualenv.exe and write last argument (presumably 
# your virtualenv name) to the file: $HOME/.virtualenv.
function ven { if( $args.count -eq 0) {Get-Content ~/.virtualenv } else {virtualenv.exe "$args"; Write-Output ("{0} `t{1}" -f $args[-1],$PWD) | Out-File -Append $HOME/.virtualenv }}

# List what's in the file or the directories under ~/.virtualenvs
function lsven { try {Get-Content ~/.virtualenv } catch {Get-ChildItem ~\.virtualenvs -Directory | Select-Object -Property Name } }

_{WARNING: This will write to ~\.virtualenv...}

I know this questions has been answered, however the reason this is happening to you, was probably because you did not add your username to the docker group.

Here are the steps to do it:

Add the docker group if it doesn't already exist:

sudo groupadd docker

Add the connected user ${USER} to the docker group. Change the user name to match your preferred user:

sudo gpasswd -a ${USER} docker

Restart the Docker daemon:

sudo service docker restart

If you are on Ubuntu 14.04-15.10* use docker.io instead:

sudo service docker.io restart

(If you are on Ubuntu 16.04 the service is named "docker" simply)

Either do a newgrp docker or log out/in to activate the changes to groups.

It's just more versatile if you give it a class name as the style you specify will only apply to that class name. But if you exactly know every .column img and want to style that in the same way, there's no reason why you can't use that selector.

The performance difference, if any, is negligible these days.

What I do is to recognize everything, and when I have the text, I take out all the characters except numbers

//This replaces all except numbers from 0 to 9
recognizedText = recognizedText.replaceAll("[^0-9]+", " ");

This works pretty well for me.

All the code is client side, I hope you fine this helpful:

First thing there are 3 functions we will use:

    function setCookie(c_name, value, exdays) {
            var exdate = new Date();
            exdate.setDate(exdate.getDate() + exdays);
            var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
            document.cookie = c_name + "=" + c_value;
        }

    function getCookie(c_name) {
        var i, x, y, ARRcookies = document.cookie.split(";");
        for (i = 0; i < ARRcookies.length; i++) {
            x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
            y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
            x = x.replace(/^\s+|\s+$/g, "");
            if (x == c_name) {
                return unescape(y);
            }
        }
    }

    function DeleteCookie(name) {
            document.cookie = name + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';
        }

Now we will start with the page load:

$(window).load(function () {
 //if IsRefresh cookie exists
 var IsRefresh = getCookie("IsRefresh");
 if (IsRefresh != null && IsRefresh != "") {
    //cookie exists then you refreshed this page(F5, reload button or right click and reload)
    //SOME CODE
    DeleteCookie("IsRefresh");
 }
 else {
    //cookie doesnt exists then you landed on this page
    //SOME CODE
    setCookie("IsRefresh", "true", 1);
 }
})

• What does the ENABLE_BITCODE actually do, will it be a non-optional requirement in the future?

I'm not sure at what level you are looking for an answer at, so let's take a little trip. Some of this you may already know.

When you build your project, Xcode invokes clang for Objective-C targets and swift/swiftc for Swift targets. Both of these compilers compile the app to an intermediate representation (IR), one of these IRs is bitcode. From this IR, a program called LLVM takes over and creates the binaries needed for x86 32 and 64 bit modes (for the simulator) and arm6/arm7/arm7s/arm64 (for the device). Normally, all of these different binaries are lumped together in a single file called a fat binary.

The ENABLE_BITCODE option cuts out this final step. It creates a version of the app with an IR bitcode binary. This has a number of nice features, but one giant drawback: it can't run anywhere. In order to get an app with a bitcode binary to run, the bitcode needs to be recompiled (maybe assembled or transcoded… I'm not sure of the correct verb) into an x86 or ARM binary.

When a bitcode app is submitted to the App Store, Apple will do this final step and create the finished binaries.

Right now, bitcode apps are optional, but history has shown Apple turns optional things into requirements (like 64 bit support). This usually takes a few years, so third party developers (like Parse) have time to update.

• can I use the above method without any negative impact and without compromising a future appstore submission?

Yes, you can turn off ENABLE_BITCODE and everything will work just like before. Until Apple makes bitcode apps a requirement for the App Store, you will be fine.

• Are there any performance impacts if I enable / disable it?

There will never be negative performance impacts for enabling it, but internal distribution of an app for testing may get more complicated.

As for positive impacts… well that's complicated.

For distribution in the App Store, Apple will create separate versions of your app for each machine architecture (arm6/arm7/arm7s/arm64) instead of one app with a fat binary. This means the app installed on iOS devices will be smaller.

In addition, when bitcode is recompiled (maybe assembled or transcoded… again, I'm not sure of the correct verb), it is optimized. LLVM is always working on creating new a better optimizations. In theory, the App Store could recreate the separate version of the app in the App Store with each new release of LLVM, so your app could be re-optimized with the latest LLVM technology.

In my case the /var/www/html in not a directory but a symbolic link to the /var/app/current, so you should change the real directoy ie /var/app/current:

sudo chown -R ec2-user /var/app/current
sudo chmod -R 755 /var/app/current

I hope this save some of your times :)

Check this post, helped me a lot. In short, the best option for me was:

import random 
import string 

# defining function for random 
# string id with parameter 
def ran_gen(size, chars=string.ascii_uppercase + string.digits): 
    return ''.join(random.choice(chars) for x in range(size)) 

# function call for random string 
# generation with size 8 and string  
print (ran_gen(8, "AEIOSUMA23")) 

Because I needed just 4-6 random characters instead of bulky GUID.

The following program calculates nCr in an efficient manner (compared to calculating factorials etc.)

import operator as op
from functools import reduce

def ncr(n, r):
    r = min(r, n-r)
    numer = reduce(op.mul, range(n, n-r, -1), 1)
    denom = reduce(op.mul, range(1, r+1), 1)
    return numer // denom  # or / in Python 2

As of Python 3.8, binomial coefficients are available in the standard library as math.comb:

>>> from math import comb
>>> comb(10,3)
120

In PHP, single quote text is considered as string value and double quote text will parse the variables by replacing and processing their value.

$test = "variable";
echo "Hello Mr $test"; // the output would be: Hello Mr variable
echo 'Hello Mr $test'; // the output would be: Hello Mr $test

Here, double quote parse the value and single quote is considered as string value (without parsing the $test variable.)

Yes, this is possible and I would like to provide a slight alternative to Rajeev's answer that does not pass a php-generated datetime formatted string to the query.

The important distinction about how to declare the values to be SET in the UPDATE query is that they must not be quoted as literal strings.

To prevent CodeIgniter from doing this "favor" automatically, use the set() method with a third parameter of false.

$userId = 444;
$this->db->set('Last', 'Current', false);
$this->db->set('Current', 'NOW()', false);
$this->db->where('Id', $userId);
// return $this->db->get_compiled_update('Login');  // uncomment to see the rendered query
$this->db->update('Login');
return $this->db->affected_rows();  // this is expected to return the integer: 1

The generated query (depending on your database adapter) would be like this:

UPDATE `Login` SET Last = Current, Current = NOW() WHERE `Id` = 444

Demonstrated proof that the query works: https://www.db-fiddle.com/f/vcc6PfMcYhDD87wZE5gBtw/0

In this case, Last and Current ARE MySQL Keywords, but they are not Reserved Keywords, so they don't need to be backtick-wrapped.

If your precise query needs to have properly quoted identifiers (table/column names), then there is always protectIdentifiers().

Go to resources folder where the application.properties is present, update the below code in that.

Actually, you are quite right when it comes to header/footer. Here is some basic information on how each of the major HTML5 tags can/should be used (I suggest reading the full source linked at the bottom):

section – Used for grouping together thematically-related content. Sounds like a div element, but it’s not. The div has no semantic meaning. Before replacing all your div’s with section elements, always ask yourself: “Is all of the content related?”

aside – Used for tangentially related content. Just because some content appears to the left or right of the main content isn’t enough reason to use the aside element. Ask yourself if the content within the aside can be removed without reducing the meaning of the main content. Pullquotes are an example of tangentially related content.

header – There is a crucial difference between the header element and the general accepted usage of header (or masthead). There’s usually only one header or ‘masthead’ in a page. In HTML5 you can have as many as you want. The spec defines it as “a group of introductory or navigational aids”. You can use a header in any section on your site. In fact, you probably should use a header within most of your sections. The spec describes the section element as “a thematic grouping of content, typically with a heading.”

nav – Intended for major navigation information. A group of links grouped together isn’t enough reason to use the nav element. Site-wide navigation, on the other hand belongs in a nav element.

footer – Sounds like its a description of the position, but its not. Footer elements contain informations about its containing element: who wrote it, copyright, links to related content, etc. Whereas we usually have one footer for an entire document, HTML5 allows us to also have footer within sections.

Source: https://clzd.me/html5-section-aside-header-nav-footer-elements-not-as-obvious-as-they-sound/

Additionally, here's a description on article, not found in the source above:

article – Used for element that specifies independent, self-contained content. An article should make sense on its own. Before replacing all your div’s with article elements, always ask yourself: “Is it possible to read it independently from the rest of the web site?”

bit long, it works i guess...

prices = [5, 12, 45]
names = []
for i, _ in enumerate(prices):
    names.append("price"+str(i+1))
dict = {}
for name, price in zip(names, prices):
    dict[name] = price
for item in dict:
    print(item, "=", dict[item])

You can use lodash's method, it works for string, number and boolean type

_.compact([0, 1, false, 2, '', 3]);
// => [1, 2, 3]

https://lodash.com/docs/4.17.15#compact

container class has 15px left & right padding, so if you want to remove this padding, use following, because row class has -15px left & right margin.

<div class="container">
  <div class="row">
     <img class='img-responsive' src="#" alt="" />
  </div>
</div>

Although most questions sort of answered the OP, I just had to go through this myself and without even googling I was able to find the quickest and simplest solution. Here's simple steps:

• copy existing .gitconfg from your other repo
• paste into your newly added repo
• change values in .gitconfig file, such as name, email and username [user] name = John email = [email protected] username = john133
• add filename to .gitignore list, to make sure you don't commit .gitconfig file to your work repo

If you want to inspect html, css or maybe you need js console in your mobile browser . You can use excelent tool eruda Using it you have the same Developer Tools on your mobile browser like in your desctop device. Dont forget to upvote :) Here is a link https://github.com/liriliri/eruda

ISO C states what the differences are.

The int data type is signed and has a minimum range of at least -32767 through 32767 inclusive. The actual values are given in limits.h as INT_MIN and INT_MAX respectively.

An unsigned int has a minimal range of 0 through 65535 inclusive with the actual maximum value being UINT_MAX from that same header file.

Beyond that, the standard does not mandate twos complement notation for encoding the values, that's just one of the possibilities. The three allowed types would have encodings of the following for 5 and -5 (using 16-bit data types):

        two's complement  |  ones' complement   |   sign/magnitude
    +---------------------+---------------------+---------------------+
 5  | 0000 0000 0000 0101 | 0000 0000 0000 0101 | 0000 0000 0000 0101 |
-5  | 1111 1111 1111 1011 | 1111 1111 1111 1010 | 1000 0000 0000 0101 |
    +---------------------+---------------------+---------------------+

• In two's complement, you get a negative of a number by inverting all bits then adding 1.
• In ones' complement, you get a negative of a number by inverting all bits.
• In sign/magnitude, the top bit is the sign so you just invert that to get the negative.

Note that positive values have the same encoding for all representations, only the negative values are different.

Note further that, for unsigned values, you do not need to use one of the bits for a sign. That means you get more range on the positive side (at the cost of no negative encodings, of course).

And no, 5 and -5 cannot have the same encoding regardless of which representation you use. Otherwise, there'd be no way to tell the difference.

As an aside, there are currently moves underway, in both C and C++ standards, to nominate two's complement as the only encoding for negative integers.

This is a variation on hexacyanide's answer above. This middleware also handles the 'data' event but does not wait for the data to be consumed before calling 'next'. This way both this middleware and bodyParser may coexist, consuming the stream in parallel.

app.use(function(req, res, next) {
  req.rawBody = '';
  req.setEncoding('utf8');

  req.on('data', function(chunk) { 
    req.rawBody += chunk;
  });

  next();
});
app.use(express.bodyParser());

Enter cron using sudo:

sudo crontab -e

Add a command to run upon start up, in this case a script:

@reboot sh /home/user/test.sh

Save:

Press ESC then :x to save and exit, or hit ESC then ZZ (that's shift+zz)

Test Test Test:

1. Run your test script without cron to make sure it actually works.

2. Make sure you saved your command in cron, use sudo crontab -e

3. Reboot the server to confirm it all works sudo @reboot

I get no output when my Test/Test Settings/Default Processor Architecture setting and the assemblies that my test project references are not the same. Otherwise Trace.Writeline() works fine.

You can simply save your data in a variable and use find(to get single object of records) or filter(to get single array of records) method of JavaScript.

For example :-

let data = {
 "list": [
   {"name":"my Name","id":12,"type":"car owner"},
   {"name":"my Name2","id":13,"type":"car owner2"},
   {"name":"my Name4","id":14,"type":"car owner3"},
   {"name":"my Name4","id":15,"type":"car owner5"}
]}

and now use below command onkeyup or enter

to get single object

data.list.find( record => record.name === "my Name")

to get single array object

data.list.filter( record => record.name === "my Name")

This is a solution based on Peter Stegnar's accepted answer.

I used it, but (as andygjp and John Saunders remarked) his code ignores attributes.

I needed to take care of attributes too, so I adapted his code. Andy's version was Visual Basic, this is still c#.

I know it's been a while, but perhaps it'll save somebody some time one day.

    private static XElement RemoveAllNamespaces(XElement xmlDocument)
    {
        XElement xmlDocumentWithoutNs = removeAllNamespaces(xmlDocument);
        return xmlDocumentWithoutNs;
    }

    private static XElement removeAllNamespaces(XElement xmlDocument)
    {
        var stripped = new XElement(xmlDocument.Name.LocalName);            
        foreach (var attribute in
                xmlDocument.Attributes().Where(
                attribute =>
                    !attribute.IsNamespaceDeclaration &&
                    String.IsNullOrEmpty(attribute.Name.NamespaceName)))
        {
            stripped.Add(new XAttribute(attribute.Name.LocalName, attribute.Value));
        }
        if (!xmlDocument.HasElements)
        {
            stripped.Value = xmlDocument.Value;
            return stripped;
        }
        stripped.Add(xmlDocument.Elements().Select(
            el =>
                RemoveAllNamespaces(el)));            
        return stripped;
    }

grep -r -e string directory

-r is for recursive; -e is optional but its argument specifies the regex to search for. Interestingly, POSIX grep is not required to support -r (or -R), but I'm practically certain that System V grep did, so in practice they (almost) all do. Some versions of grep support -R as well as (or conceivably instead of) -r; AFAICT, it means the same thing.

This issue is occurring because we don't have Entity Framework installed. Please install Entity Framework using the below command.

Install-Package EntityFramework -IncludePrerelease

Once installed, choose the project in the package manger console default project drop down.

Make sure at least one class in your project inherits from data context, otherwise use the below class:

public class MyDbContext : DbContext
    {
        public MyDbContext()
        {
        }
    }

If we don't do this we will get another error:

No context type was found in the assembly

After completing these things you can run

On python 3.5+ there is an easier way to achieve a shallow copy by using the ** unpackaging operator. Defined by Pep 448.

>>>dict1 = {"key1": "value1", "key2": "value2"}
>>>dict2 = {**dict1}
>>>print(dict2)
{'key1': 'value1', 'key2': 'value2'}
>>>dict2["key2"] = "WHY?!"
>>>print(dict1)
{'key1': 'value1', 'key2': 'value2'}
>>>print(dict2)
{'key1': 'value1', 'key2': 'WHY?!'}

** unpackages the dictionary into a new dictionary that is then assigned to dict2.

We can also confirm that each dictionary has a distinct id.

>>>id(dict1)
 178192816

>>>id(dict2)
 178192600

If a deep copy is needed then copy.deepcopy() is still the way to go.

Although already answered, and author's intent is to create a front controller type app but I am posting literal rule for problem asked. if someone having the problem for same.

RewriteEngine On
RewriteRule ^([^/]+)/([^/]+)/([\d]+)$ $1?id=$3 [L]

Above should work for url picture.php/Some-text-goes-here/51. without using a index.php as a redirect app.

It should be this way:

h2.myClass looks for h2 with class myClass. But you actually want to apply style for h2 inside .myClass so you can use descendant selector .myClass h2.

h2 {
    color: red;
}

.myClass {
    color: green;
}

.myClass h2 {
    color: blue;
}

Demo

This ref will give you some basic idea about the selectors and have a look at descendant selectors

Actually the only two strategies you would want to choose are ours if you want to abandon changes brought by branch, but keep the branch in history, and subtree if you are merging independent project into subdirectory of superproject (like 'git-gui' in 'git' repository).

octopus merge is used automatically when merging more than two branches. resolve is here mainly for historical reasons, and for when you are hit by recursive merge strategy corner cases.

Simple input[name=Sex][value=M] would do pretty nice. And it's actually well-described in the standard doc:

Multiple attribute selectors can be used to refer to several attributes of an element, or even several times to the same attribute.

Here, the selector matches all SPAN elements whose "hello" attribute has exactly the value "Cleveland" and whose "goodbye" attribute has exactly the value "Columbus":

span[hello="Cleveland"][goodbye="Columbus"] { color: blue; }

As a side note, using quotation marks around an attribute value is required only if this value is not a valid identifier.

JSFiddle Demo

I think you can achieve this the quickest by using the where function:

For example looking for items greater than 0.2 in a numpy array and replacing those with 0:

import numpy as np

nums = np.random.rand(4,3)

print np.where(nums > 0.2, 0, nums)

I'm guessing that you don't need to re-increment the existing data so, why can't you just run a simple ALTER TABLE command to change the PK's attributes?

Something like:

ALTER TABLE `content` CHANGE `id` `id` SMALLINT( 5 ) UNSIGNED NOT NULL AUTO_INCREMENT 

I've tested this code on my own MySQL database and it works but I have not tried it with any meaningful number of records. Once you've altered the row then you need to reset the increment to a number guaranteed not to interfere with any other records.

ALTER TABLE `content` auto_increment = MAX(`id`) + 1

Again, untested but I believe it will work.
